this is john kohler with growingyourgreens.com.i'm grateful we have a break in the weather. it's been raining for like the last 2 daysstraight and i haven't been able to get out to do a show for you guys, but i'm back today,and we're going to talk about an important subject that both you and i ad our plantsare made of, and that's calcium. calcium is a real important nutriment. it's like thebackbone to our plants and literally it is the backbone to us. calcium is the most abundantmineral in the body. you know, our bones, our teeth, you know, we need calcium to bestrong. many people in our society or many companies would want you to think, 'hey, drinkmilk for calcium!' do we need to get calcium from our milk? you know what, let me tellyou something. the bok choy right here in
front of you that i grew has 4 times as muchcalcium as milk. 4 times! so there's 4 times as much calcium than the milk by calorie.so, do you want to eat something that has 4 times the amount of calcium or 1 time? so,bok choy has way more calcium than the milk. alright, so now i'm standing here in frontof my broccoli, and did you know that broccoli has 2 times the amount of calcium by calorieas milk does? so, that's 2 times the amount of calcium, twice as much, in broccoli. so,this is broccoli that is going to flower. you know, the heads usually are tighter thenthey start to open up and start to flower, but, you know, these are edible. it tastesjust like broccoli and the one thing you don't know about, that most people don't know about,is that these are the broccoli leaves. they
look like kale leaves and you can use themas such. you can eat them raw or juice 'em or blend 'em, cook 'em up or whatever, but,you know, they have 2 times as much calcium as milk by calorie. so, i'm sitting here nextto some of my favorite green sin the world. these are collards. i'm not sure, but theseare probably georgia collards. i love georgia collards. they're one of my favorites. youcan use them as wraps or a variety of other things, but guess how much calcium collardshave. well, they have almost 3 times as much calcium as milk. now we're in my back yardand one of my favorite greens that's really rich in calcium: arugula. so, this is my arugula.it's starting to go to flower now. some of the ones in the front have already gone toflower now, and actually some of the ones
in the front have actually gone to seed pod,they're actually making seed pods now. these are some arugula leaves, and this stuff isreally rich in calcium. it's probably one of the richest plant sources of calcium. thishas 6 times more calcium than milk by calorie. so, arugula's really rich in calcium, andthe other things is, you saw, you know, arugula has 6 times, bok choy has 4 times, collardshave 3 times, broccoli has 2 times, and, you know, while these leafy greens that i mentionedhave more calcium than milk, many other leafy greens, you know plants, fruits and vegetables,also have calcium, but these are the extreme examples that have a lot more than milk. whilewe're talking about that, i want to ask, what is the calcium in the milk come from? well,it comes from the cow, right? well, yes, the
milk comes out of the cow, but the cow didn'tjust automatically make the calcium. i mean, people can't really make minerals happen.i wish. so, the cow got the calcium from somewhere. so, in nature cows would naturally eat grass,for example. so, cows eat grass, and grass has calcium. we can also eat grass. i don'trecommend doing that unless maybe you're juicing it, but the cow is getting the calcium fromthe grass, it's processing, and it gives the milk the calcium that is from the grass. so,we could eat the grass or other plants to get the calcium first hand instead of gettingthe calcium second-hand. that is what the show's about today. growing your calcium.so, have you ever taken a calcium supplement? i mean, that's where we're supposed to getour calcium form, right? a supplement. well,
maybe not. maybe we should be getting calciumform our foods, and, you know, as i've mentioned, all our foods, you know, a lot the greenshave calcium, and actually a lot more calcium than milk as i've just share with you, butwhere does the plant get its calcium from? well, the plants get calcium from the soil.so, it's very important that you soil is nutritious for the plants. if you're just growing in,the extreme example could be, sand or clay, there's not a lot of nutrition in that. so,you want to be adding some calcium back into the soil so your plants will have nutrition.i mean, calcium's just one mineral. there's so many minerals on the earth. the questionis, 'should i even be adding minerals back into my soil, john?' well, i have this here,and this is actually form the 74th congress
senate. this is actually a document form thesantã©, document 274 form the 74th congressional section. let's see, june 1st, 1936, by theunited states government printing office. 1936, washington d.c. so, according to thisdocument here, printed in 1936, it's basically about minerals and how our soils are devoidof minerals. i'll just read the last paragraph here, for fun. it goes on to say that, youknow, the soils are devoid of minerals, and the last paragraph is this. 'the public canhelp. it can hasten the change.' so, they're saying, you know, we really need to act onthe soils deficient minerals, and that the public can help, and here's how. 'how? bydemanding quality in its food. by insisting that our doctors and our health departmentsestablish standards of nutritional value.'
which we know they did. we have the usda andthe food pyramid and we have what the recommended daily allowance is, and it says, 'the growerswill quickly respond. they can put back those minerals almost over night and by doing sothey can actually make money by bigger and better crops. it is simpler to cure sick soilsthan sick people. which shall we choose?' i don't know, do we have sick soils or sickpeople in our society today? well, i don't know. there's a lot of sickness. healthcarewas a big debate. i'm not even going to get into that, but, you know, healthcare's hugeand part of the problem may be that there's not enough minerals in the soils. we've been3 major minerals back into the soils. npk, which is what major growers do and they alot of herbicides, pesticides, fungicides,
and all kinds of other things just to makethe crops grow, and it gives them pretty good yields, but there has been companies i'veheard, you know, some companies like, well i won't mention any name, but some big organiccompanies that started to grow carrots using rock dust, and this is just one kind of rockdust, azomite, which adds minerals back into the soil, and their yields actually, i won'tsay went through the roof, but actually significantly increase and were actually viable so thatthey actually now use rock dust as a standard practice form what i hear, because it increasedtheir yields and made it financially viable to put in their fields and made the crop muchmore than the price or the rock dust, or adding the rock dust minerals back into the soil.i've been a big advocate of rock dust, you
know, for as long as i've been growing becauseof my friend don weaver. you can check out his website, remineralize.org for some informationon rock dust. i will soon also be having a show specifically on the rock dust that addsnot only the calcium but also all the other minerals and how much rock dust should youadd? because this is literally powdered rock, it's not just rock, it's how minerals naturallyoccur in the soil, you now, that the rocks were ground up and put into the soil. a recommendedapplication rate according to the manufacturers is like 1 pound per every 10 square feet oryou might do 1 and half or 2 pounds to make it go a little but higher, but i do a littlebut more than that. so, i also have here some shell flour, and this is a calcium supplement.so, i do recommend that you get your soils
tested and if your soils don't have enoughcalcium in 'em to add specifically a calcium supplement. i was surprised because i'd beenadding rock dust all these years and i still didn't have enough calcium in my soils foroptimal production and optimum soil fertility because soil fertility is very important becausethe rock dust has just, you know a percentage. 1.8% of calcium, so it's really not that much.these are, once again, trace minerals. it's not going to do anything for you if you havereally, you know, off the charts or really abnormal low amounts of a mineral. so, that'swhy i'm going to get the oyster shell calcium which is just basically ground up oyster shellsand other shells, and this is actually locally produce in panouma, and that's just 10 milesaway. so, it can be more sustainable because
it's a locally grown product. i'm going toadd this calcium back to my soils, but i'm also goanna raise my bricks. i did have oneepisode about raising bricks and i hope to have a couple more talking about bricks, butbricks is not only the sheer content and taste of your produce, but also the mineral contentof the produce. you can tell that by looking a bricks test. so, hopefully you've learnedmore today about calcium and why your soils need calcium and how you can grow your owncalcium in your garden and maybe not need to drink as much milk. this is john kohlerwith growingyourgreens.com, with chico. he wants to say hi. say hi chico. alright, sowe'll see you next time.
